This invention relates to and has for a principal object the provision of an improved method and means for mounting tile on sheets or panels for use in ornamenting, finishing or decoratinginterior wall surfaces.

My invention comprehends the arrangement of tile in ornamental or-decorativeeffects on a substantially non-expansible sheet of material such as ply wood, plaster, or composition lath, or other material, whereby the tile may be applied to a wall in prearranged panels more economically than by the ordinary methods of individually applying the tile as in ordinary cases. It is also an object of my invention to provide a tile structure comprising a substantially non-expansible back which is first coated with a semi-plastic adhesive substance and is thereafter covered with a sheet or sheets of fabric such as burlap to which the hard tiles are applied by first coating the outer surface of the fabric with a likecement and pressing the tiles firmly onto the fabric. Thus I am enabled to provide a fabric cushion '25 which is more or less flexible and expansible between the substantially back and'the hard tiles.

'The cement. employed for attaching the fabric to the back and the tiles to the fabric is moisture-proof so as to exclude moisture from the'back or carrier.

non-expansible Other objects may appear as the description progresses.

I'have illustrated my invention in the accompanying drawing, in which Fig. 1 is a plan or face view of a portion of a tile panel constructed in accordance with my invention. I

Fig. 2 is an enlarged transverse section of the same on line 2-2 of Fig. 1, showing a sheet of fabric employed as a cushion between the tile and the supporting surface. Y

TILE BOARD 1930. Serial No. 440,980;

lieu of the fabric or woven material shown in Fig. 2.

Fig. 4 is a view similar to Fig. 2 but showing a back formed of plaster board for composite material such as is used for wall board, lath, and the like, in lieu of the wood backing shown in Figs. 2 and 3.

In the practice of my invention, I propose to utilize multiple ply wood sheets 1, as shown in Figs. 2 and 3, or plaster board or sheets of composite material in lieu of the ply board, as shown in Fig. 4. When the ply board is used as a back it'may consist of a plurality of plies, as at 2, 3 and 4 with the grain of the alternate sheets or plies arranged at right angles to each other.

Thus the wood back 1 is substantially nonexfiiansible. The backs lare then coated to a su cient thickness with v a semi-plastic cement, as at 5, after which a sheet or sheets of coarsely woven fabric 6, such as burlap or fibrous material such as felt, are applied to the coating 5 of cement, and by suitable means are smoothed out by pressure or otherwise so as to present a smooth surface for the reception of the blocks of tile.

The fabric or fibrous material 6 forms an expansible cushion material for the tile blocks, and said blocks are applied to the fabric or fibrous material 6 by thoroly coating the outer surface of the material 6 with a semiplastic cement as at 7, after which the tile ings. The usual pointin 9 of suitable material may be employe between the tile blocks 8. p

The cement employed for attaching the material 6 to the back 1 and also for attaching the tile blocks to the material 6 is semiplastic in character, i. e. to say, after the cement has hardened it will still retain a certain amount of flexibility or ductility. Preferably the cement embodies certain vegetable and mineral ingredients for lending tenacity, body, and resiliency thereto. The cement employed .should also be of such cha racter that it will adhere equally as well to composition materials as to wood, and should be waterproof and bacteria-proof soas to prevent deterioration of the tile panels after they have been set u in a-wall.

The back 1 should e of such character that it will be proof against distortion, warping, swelling, expansion and contraction in order to prevent the cracking or breaking apart of the tile blocks 'on the anels.

The exposed surfaces 0 the back 1 may be coated with any suitable'material such as shellac to prevent the entrance of moisture into the pores of the backing material. At the edges of. the composite panels the cement may overlap the edge of the cushion material 6 so as to prevent the entrance of moisture thereto.

It will be apparent that an assembled tile panel of the character shown and described will be proof against warping, distortion or breakage of the tile by reason of the interposition between the back and the tiles of the resilient, flexible and expansible sheets of material 6. Said material being loosely woven or fibrous, is of itself highly flexible,

resilient and eXpansible, but when held'between-the two coatings 5 and 7 of 'semiplastic cement these characteristics of thematerial 6 are substantiallymodified, and the tendency to stretch and distort are counteracted. The semi-plastic cement coats 5 and 7, however, being somewhat resilient, permit of a sufficient expansion and contraction of the material 6 to off set any change which may be effected by moisture or any slight expansion or contraction of the back 1 by changes of temperature or conditions of extreme dryness or extreme moisture.

formed of a substantially non-expansible' back, a coating of semi-plastic cement on a surface thereof, a sheet; of fibrous material applied over said coating of cement, a coating of semi-plastic cement over the surface of said fibrous material, and a facing of tile applied to said last mentioned coating of cement.

'3. A wall structure comprising a panel formed of a substantially non-expansible back,,i fibrous cushion applied to a surface of saidback, a coating of semi-plastic cement applied to the outer surface .of said cushion, and a facing of tile applied to said coating of cement.

4. A wall structure comprising a panel formed of a substantially non-expansible ROY e. STANBROUGH.

The method and means for constructing tile panels which have been illustrated and described herein are therefore admirably adaptr ed for use in producing interior decorative effects as'well as for exterior use, and the construction of the panels at the factory in pre' determined designs and in suitable sizes substantially reduces the cost of applying a tile finish to wall surfaces.

While ply wood or composition panels, as I at 1, are substantially stiff and proof against warping and distortion, I may provide any suitable means on the backs of said panel for additionally stiffening the same, as taught by others in the art. 1

Other objects and advantages will readily appear. to those familiar with the design, structure and use of such structures.

' What I claim is: I

1. A wall structure comprising a panel having a non-expansible back, a cushionof fibrous material adhesively applied to said back, and a facing of tile adhesively applied to the outer surface of said cushion material.

2. A. wall structure comprising a panel-
